indexOf not working

var myurl = window.location;
    var pos = myurl.IndexOf("memberId");
    if (pos = -1) {
        alert("false");
    } else {
        alert("true");

For some reason I can't seem to get this simple method to work. Chrome says 'myurl does not contain the method 'indexOf''. Any reason?

Maybe typo but it should be

myurl.indexOf

lowercase i.

And location is an object, so you want:

var myurl = window.location.href;

(and all the other things people say in the comments and other answers ;))

Update: To see what kind of properties an object has, just type, in this case, window.location in the console:

window.location returns an object. Perhaps you wanted window.location.pathname? :-)

There's also a problem with this line:

if (pos = -1)

It should be

if (pos == -1)

try var myurl = window.location.pathname;

var myurl = window.location.toString();
